The AirTAC GFR600C20ALJC2WK AirTAC Low-Pressure Filter Regulator 3/4" is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600C20ALJC2WK is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at a set point, in a single body. This 600-size unit is fitted with PT3/4 ports, a 5 um filter element (code W), an automatic drain, and the low-pressure regulator type. At size 600 the bowl is aluminium alloy, a round external gauge scaled in psi is fitted, and a reverse/check valve is included; no mounting bracket is supplied with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and catalogue options for manual or differential-pressure drains, 40 um or 5 um filtration, square or round gauges in MPa, psi or bar scales, G (BSPP) or NPT threads, and a reverse valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding air-jet looms and spinning-room auxiliary lines from a plant ring main, where loom air is regulated at low set points and the 5 um element keeps scale and pipe debris away from jet nozzles and sensitive guides.
Regulating atomizing and conveying air to spray guns and coating stations, where the low-pressure regulator type matches low set points and the 5 um element with automatic drain keeps water and particulate out of the finish air.
Supplying cylinder-driven gating, capping and pusher stations on a bottling or packaging line; the 3/4 inch PT port and 600 size serve higher-demand manifolds, and the fitted reverse/check valve guards the circuit against backflow.
Size the unit by port and demand: 600 is the largest GFR size, here with a 3/4 inch PT port, and the right step depends on the air consumption of your line. Flow is published as curves, not a single rating, so ask us to check the curve against your requirement before ordering. This configuration carries the low-pressure regulator type, whose exact adjustment range is not published - confirm it with us if your set point is specific; standard-range GFR versions regulate 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains.
Other decodable choices on this family: the 5 um element (W) versus the standard 40 um; the automatic drain fitted here versus manual (M) or differential-pressure (blank); a round gauge scaled in psi versus the embedded square gauge in MPa, psi or bar; PT thread as the standard, with G (BSPP) and NPT as order options; and no bracket (code J), so plan your own mounting. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature -5 to 70 C, non-freezing.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, set point and air consumption, and we will confirm from the datasheet whether this 600-size, 3/4 inch unit is correctly sized for your application.
The automatic drain (code A) expels collected condensate from the aluminium alloy bowl without daily attention. Manual (M) and differential-pressure (blank) drains are catalogue options on the GFR family if you prefer controlled or energy-saving draining - just specify the code when ordering.
